In the case of perforated belts please note: calculate the load-bearing belt width b 0 based on the number of per-forations which decrease cross sec-tions. Staggered perforations in partic-ular can reduce the load-bearing belt width considerably. Reduce the figure for the load-bearing belt width b 0 by a further 20 % to take tolerances for per-

lated overhung load, it also potentially reduces the required belt width. Reducing the belt width and mounting the sprocket as close as possible to the outermost bearing of the speed reducer both move the center of the belt load closer to the speed reducer. This also reduces the calcu-lated overhung load. Alterations to the belt drive design

Belt Length Calculator

How to compute like our belt length calculator? Let's say that you own a factory and you need to calculate a v-belt length. The diameters of the pulleys are 15 and 30 cm, and you want the distance between them to be 1.5 meters. D L = 30 c m = 0.3 m. small text {D}_text {L} = 30space cm = 0.3space m DL. .

Motor Sizing Basics Part 1: How to Calculate Load Torque

To calculate load torque, multiply the force (F) by the distance away from the rotational axis, which is the radius of the pulley (r) . If the mass of the load (blue box) is 20 Newtons, and the radius of the pulley is 5 cm away, then the required torque for the application is 20 N x 0.05 m = 1 Nm. Typically, a safety factor is used so that the ...
